We disclose a medical toilet that comprises one or more medical devices and a control for the metrics they collect. The medical devices may be used to collect metrics relevant to a user's health status. The medical toilet further comprises a conduit through which volatile organic compounds travel from the toilet bowl to the environment outside the toilet. An animal trained to identify the scent of bodily waste collected from a user that is afflicted with a disease perceives the scent of the user's bodily waste traveling through the conduit and performs a defined act upon perceiving the disease scent. The metric collected by the medical device(s) may be used to diagnose the same disease as that which the animal is trained to identify. The diagnosis provided by the animal by way of the conduit acts as a control for the metric collected by the medical device.

This invention relates to a device for diagnosing disease and use thereof.
Many animals have heightened senses relative to humans. In fact, humans have used the relatively enhanced ability to see, hear, and smell of animals to perform tasks for hundreds of years. In particular, dogs have been used for their enhanced sense of smell to assist in tasks that include hunting, protecting livestock from predators, searching for specific humans, and detecting illegal substances. More recently, evidence has been reported that dogs have predicted seizures before they happened and identified cancer. Other organisms, including rats, mice, and insects show behavior that suggests they can identify a diseased organism.
It is unclear what substances animals smell when they identify disease. Furthermore, studies show that a variety of biological substances collected from a diseased human emit substances that animals distinguish from those of healthy humans. Reports of animals identifying disease include those in which the animal evaluated feces, urine, blood, and exhaled breath. Each of these biological substances emit volatile organic compounds (VOCs). It is likely that the biological samples the animals identify as those from a diseased human emit a plurality of different VOCs. It may be this combination that the animal perceives as the scent of disease. By smelling the combination of molecules that collectively identify disease, the animal may be able to diagnose with more sensitivity and specificity than available laboratory assays.
Furthermore, the animal's sense of smell identifies a marker of disease through a different mechanism than those employed by medical devices. Consequently, diagnosis by an animal may be a valuable method to confirm a diagnosis made through other methods.
Every method of measuring physiological functions has inherent limitations. Medical devices may provide inaccurate results for various reasons including user error, damaged components, or attempts to use the device under conditions for which it was not designed. Consequently, it is beneficial to have a control diagnostic test to compare to a health metric collected from a medical device to confirm the result obtained from the medical device. Furthermore, it is preferable that the control diagnostic test perform the assessment of the user's health status through a different mechanism than the health metric collected by the medical device.
To address this problem, we disclose a medical toilet that includes a scent dispenser which may be used as a control diagnostic test for a health metric collected by the medical toilet. The medical toilet includes at least one medical device that measures a health metric. The health metric is a measurement that may be used to assess the user's health status and/or diagnose a disease. The medical device may measure an analyte in the user's bodily waste or some other physiological characteristic or function that is an indicator of a disease.
In addition, the medical toilet includes a scent dispenser. The scent dispenser may be positioned on a side of the medical toilet and is in communication with the toilet bowl within the medical toilet. The scent dispenser comprises a conduit through which air from within the toilet bowl may travel to the environment outside the medical toilet. When bodily waste from the user is deposited into the toilet bowl, the bodily waste emits volatile organic compounds (VOCs). An animal is positioned outside the medical toilet in the vicinity of the scent dispenser. According to the invention, the animal has been trained to differentiate the scent of VOCs that emit from bodily waste that is collected from a user with a specific disease from that collected from a user that is not afflicted with that disease. The animal performs a defined act which signals to an observer that the animal has perceived the scent of VOCs associated with the disease. The disease associated with the VOCs according to the invention is the same disease as the health metric collected by the medical device is designed to measure. Consequently, the medical device and the scent dispenser provide two methods of testing a user for a disease. The scent dispenser thus functions as a control for the health metric collected by the medical device of the medical toilet.
Definitions
Toilet, as used herein, means a device that may be used to collect one or more bodily waste products of a user.
Medical toilet, as used herein, means a toilet that comprises one or more medical devices which measure physiological characteristics, physiological functions, and/or analytes within bodily waste for use in assessing a user's health status.
User, as used herein, means a human or animal that deposits bodily waste into an embodiment of the toilet disclosed herein and for which the medical toilet is used to measure physiological functions which may be used to assess the health status of the human or animal.
Healthcare provider, as used herein, means any individual who performs a task, mental or physical, in relation to health-related services provided to a user. In addition to clinicians who practice medicine directly on a user, the term healthcare provider includes any person that enters data into a computer, when the data entry is used in analysis of a user's health status or to improve a user's health.
Bodily waste, as used herein, means any one or combination of urine, feces, vomit, sputum, blood, seminal fluid, tears, nasal mucus, gastrointestinal tract mucus, urogenital tract mucus, saliva, exhaled breath, or sweat from the body of a user.
Animal, as used herein, means non-human members of kingdom Animalia, including vertebrates, invertebrates, insects, and marine organisms.
Disease, as used herein, means any disorder of structure or function in the body or a human or animal, whether or not the disorder presents with signs or symptoms.
Diseases that may be diagnosed according to the methods disclosed herein and using the medical toilet disclosed herein include, but are not limited to, colon adenoma, colon carcinoma, colon adenocarcinoma, colorectal adenoma, colorectal carcinoma, colorectal adenocarcinoma, bladder carcinoma, bladder adenocarcinoma, liver adenoma, liver carcinoma, liver adenocarcinoma, esophageal adenoma, esophageal carcinoma, esophageal adenocarcinoma, stomach adenoma, stomach carcinoma, stomach adenocarcinoma, pancreatic adenoma, pancreatic carcinoma, pancreatic adenocarcinoma, lung cancer, mouth cancer, throat cancer, inflammatory bowel disease, urinary tract infection, gastric ulcer, diabetes, hyperglycemia, hypoglycemia, impending seizure, and impending migraine.
While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, which will herein be described in detail, several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principals of the invention and is not intended to limit the invention to the illustrated embodiments.
Disclosed herein is a medical toilet, which comprises a medical device used to diagnose disease in a user. The toilet differs from those used simply to collect and dispose of urine and feces at least because it includes a scent dispenser and at least one other medical device. The scent dispenser acts as a conduit through which volatile organic compounds (VOCs) may travel from the environment inside of the toilet, for example, the toilet bowl, to the environment outside the toilet, for example, the room air.
The scent dispenser may comprise of an opening on the side of the medical toilet. Referring now to the drawings,
For use in diagnosis of disease, an animal is positioned in the vicinity of the toilet and a user deposits bodily waste into the toilet bowl. A blower may be activated through mechanisms known in the art which include the use of motion sensors which would cause a signal to be transmitted to the blower when bodily waste passes by the sensor. Alternatively, the user, or possibly even the animal, may turn the blower on or off by pressing a button or flipping a switch.
The user deposits bodily waste into the toilet through actions which include urinating or defecating into the toilet, vomiting into the toilet, coughing up sputum into the toilet, and depositing mucus into the toilet. A user may deposit nasal mucus and sputum into the toilet by coughing or blowing the user's nose into a tissue and tossing the tissue into the toilet.
An animal may be trained to sniff the scent dispenser in response to a command or signal. The user may give the animal the command or signal when the user desires the animal to assess the presence of disease in the user. Alternatively, the animal may simply be trained that the scent dispense is something that the animal should sniff and do so when placed in the proximity of the toilet. Furthermore, the animal may be an insect that is placed in a container. The container may be attached to or placed in the vicinity of the scent dispenser avoiding any need to train the animal to approach the scent dispenser.
The animal must also be trained to identify a disease by the smell of bodily waste collected from a user who has that disease and to differentiate this from scents emitted by bodily waste collected from users who do not have the disease. Furthermore, the animal must be trained to perform a behavior that functions as a signal that the animal has detected the scent of disease in the user's bodily waste. Various methods of training an animal to identify a sent emanating from bodily waste that was obtained from a diseased organism as well as methods to train the animal to provide a signal to communicate upon perceiving this particular scent are known in the art and within the scope of the methods disclosed herein.
According to the invention, the disease which the health metric collected by the medical device is designed to diagnose and that which is diagnosed when the animal responds to a scent coming through the scent dispenser are the same or similar. For example, the medical device may collect a health metric from a user's urine which is an indicator of bladder cancer. The animal may also be trained to respond to a scent it perceives when sniffing VOC's that are associated with bladder cancer. Consequently, both the medical device and the scent dispenser are used to test for the presence of bladder cancer in the user. While the health metric may be a quantitative assay conducted by measuring a known analyte, the response from the animal is a qualitative assessment which is used as a control for the quantitative health metric. Both methods answer the same question through different methods. The animal and scent dispenser, thus, provide a control diagnostic technique for the health metric which is not impacted by any defect in the medical device.
In another embodiment, the medical device collects a health metric by measuring a property of a different physiological function or different type of biological sample than the bodily waste assessed by the animal. For example, the medical device on the medical toilet may perform an electrocardiogram (EKG) measurement to assess the user's cardiovascular health. The bodily waste deposited in the toilet may emit VOCs that are indicative of myocardial damage and which the animal is trained to recognize. In this embodiment, the scent dispenser and animal provide a diagnosis based on the user's bodily waste and act as a control for a health metric that is performed on the user's heart function.
Frame 110 surrounds the perimeter of porous material 115 and may be constructed from metal, porcelain, rubber or rubberized materials, plastics that comprise of any of a variety of polymers and copolymers known in the art, glass, silicone, and ceramic. Frame 110 may be constructed of any of a variety of materials that are water resistant so as to not be damaged by exposure to toilet water. Frame 110 may include a gasket constructed of one or more of rubber, rubberized material, plastics that comprise of any of a variety of polymers and copolymers known in the art, or other materials known to prevent liquid leakage.
Frame 110 may be constructed to receive and hold frame 120, frame 120 being in combination with blotting sheet 117, such that blotting sheet 117 is positioned behind porous material 115. In one embodiment, frames 110 and 120 are constructed so that frame 120 is a cassette that slides laterally to a position within frame 110 fits within frame 110.
Blotting sheet 117 may be positioned within the medical toilet, such that toilet water or other solvent comes in physical contact with at least a part of blotting sheet 117 when a user has deposited bodily waste into the toilet. Alternatively, blotting sheet 117 may be positioned such that liquid bodily waste comes directly in physical contact with blotting sheet 117 without being diluted by solvent. For example, the user's urine stream may come in contact with blotting sheet 117.
In either scenario, blotting sheet 117 wicks the solution or liquid bodily waste so that it is spread across blotting sheet 117. VOCs evaporate into the environment outside the toilet, traveling through porous material 115. The animal is then able to smell the VOCs to assess them for the disease scent.
In the embodiment of
Alternatively, the medical device may be measuring a health metric that is not collected from the bodily waste.
